INVERTED INCANDESCENT GAS-BURNER.

Specification of Letters Patent.

Patented Dec. 29, 1908.

Application filed June 9', 1908. Serial No. 437,520.

To all whom it may concern} Be it known that I, AUGUSTINE Louis DUNPHY,a subject of the King of Great Britain and Ireland, residing at TheSouth Metropolitan Gas Com any, East Greenwich, county of Kent, Eng and,have invented certain new and useful Improvements in InvertedIncandescent Gas-Burners, of which the following is a specification.

This invention relates to improvements in inverted incandescent gasburners and has for its special objects an improved construction andarrangement whereby the glass chimney or globe may be effectuallylocked, thereby preventing all wabbling or shaking of said chimney orlobe and the provision of a simple and e 'cient means whereby theplacing of the globe in position may be effected.

The burner consists of a tube, with a. bend in it, of refractorymaterial having a nozzle with lugs to receive the mantle and a backflange to receive the chimney or globe which is of spherical or othershape with an opening at top and bottom and in its side for fixing tosaid back flange. The underside of the bent tube is provided with aprojection adapted, when the chimney or globe is being placed inposition, to come into contact with the inner wall of the chimney orglobe and to thereby prevent the chimney or globe from coming intocontact with the mantle.

Referring to the accompanying sheet of drawings :Figure 1 is a frontelevation; Fig. 2 is a vertical section; and, Fig. 3 an end view of aninverted. burner having its back flange arranged in a vertical position.Fig. 4 is a plan view thereof. Figs. 5 and 6 are side views,illustrating the burner having its back flange arranged at an angle to'the horizontal, the chimney or globe being shown in its locked position.

Like letters of reference indicate corresponding partsin the severalviews.

In said drawings a is the bent tube and l) the back flange which may bearranged in a vertical position as in Fig. 1, or inclined as in Figs. 5and 6. To connect the back flange 1) with the neck a of the chimney orglobe cl the back flange b is provided with an arched shaped groove e,the top of said arch being arranged vertically so that when the neck ofthe chimney is passed over thefront flange f and rotated the top edge gof the elliptical opening of the chimney will rest upon said arch-shapedgroove eat it, while. the sides of the elliptical opening will besecurely held between the flanges f, b and the bottom f of the groove e,when openings 0, c in the chimney are vertically one above the other,this construction preventing any shaking of the chimney or globe when inposition.

To assist in placing the chimney or globe in position the underside ofthe bent tube a is provided withan extension or lug m against which theedge of the elliptical opening in the neck of the globe or chimneyengages, said lug or extension being used as a pivot point to assist inthe turning of the globe or chimney while serving as a means to preventthe chimney or globe encountering the mantle, thereby damaging the same.Having now described my invention what I claim as new and desire tosecure by Letters Patent of the United States is 1. An invertedincandescent gas burner comprising a base, a bent tube carried thereby,said base having a back flange, and an arch shaped groove formed infront of said flange at the upper portion of the base, a globe having anelliptical opening adapted to engage with the arch shaped groove of thebase, and a lug on the under side of the bent tube to act as a turningpoint to assist in placing the globe in position. 2. An invertedincandescent gas burner comprising a base havinga flange and an upperarch sha ed portion of smaller diameter'than sair flange, flanges oneach side of said arch shaped portion forming side grooves betweenthemselves and the rear flange, a bent tube carried by said base and aglobe having an elliptical opening adapted to engage with the archshaped portion and to be held by the flanges.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
